ok so i figured out what the problem is, your gonna be ****** too. Turns out, there is nothing wrong. When you move the files, the dev kit uses so much of its memory that it basically shuts down until the files are moved over. That is why it doesnt respond. If you just let it sit for 10-15 minutes maybe, your dev kit will respond again and you will find the files in the folder you copied them too. Trust me, you just have to wait it out. Its great to learn that there is nothing really wrong, but it sucks because the contest is over and you could have built mods this whole time. I am in the same boat. hope that works for you
